What you are saying makes perfect sense but neither me nore the Lucid guy were thinking about ICE. If You think of his circles as 95% and 97% and his curve as 60 KW, his graph of electric motor looks exactly like yours. I think he was just trying to convey some general concepts to electrically challenged folks like me. But I do get your point.

Even if electric efficiency improvement is not significant, it adds up. When I keep my power band in control (under 50 KW) that motor efficiency adds to the power I am not loosing fighting air molecules at higher speed or on tire friction flooring it. So my total real life saving operating that motor in that range is much larger than 10%. I get 3.6 Kwh in my city drives vs 1.8 Kwh flooring it on the highway. 100% improvement is not too shabby. So as others have suggested, instead of worrying about mods, I just chill and enjoy the scenery.

All that said, it is fun to see how much others can eek out of the system.

Thanks for sharing. Seeing the numbers next to the lines helps clear things up a bit. Now I am thinking I should dig out the RPM numbers out of my car scanner. I always wondered what would be the appropriate speed going up a hill near my house. With your graph, even if the graph is not for Lightning Motor, having two of the variables, I should be able to make an educated guess.
The ICE portion is just to point out that electric motors dont have near the same negative effects "flooring it" as it does in an ICE vehicle. That mentality tends to carry over to discussions of efficiency in BEV vehicles.

The other thing to consider is how much time is spent accelerating compared to driving. The efficiency "loss" is only during the time of acceleration, it doesnt change steady cruising.

I'm not saying there is no impact, but the net impact is very small. The overwhelming determination for efficiency will be average speed.

Sold. I am hoping you will bail me out if I am caught for reckless driving.
